🍺 If you try just one: Wreak Havoc Imperial Red (Red Ale – Imperial/Double, ABV 8.5%) — GABF Gold 2 consecutive years & World Beer Cup Bronze 3 times. This is Bootstrap’s flagship beer.
A Small Colorado Brewery That Conquered the World
At the foot of the Rocky Mountains lies Longmont, Colorado — a town of about 100,000 people that is home to a brewery with an astonishing record of 5 GABF (Great American Beer Festival) Gold medals and 3 World Beer Cup Bronze medals. That brewery is Bootstrap Brewing.
In 2012, Leslie & Steve Kaczeus — a couple who left the high-tech industry — poured over 20 years of homebrewing experience and their dreams into a roughly 1,200-square-foot warehouse (a former plumbing business) to launch this brewery. True to the name “Bootstrap” (to pull oneself up), they grew entirely through self-funding with zero outside investment. Today, their taproom at 142 Pratt Street in downtown Longmont serves as a community hub where visitors enjoy live music, food trucks, and outstanding craft beer.
In February 2026, Bootstrap announced its membership in the Left Hand Collective (an alliance of Left Hand Brewing + Dry Dock Brewing), signaling an exciting new chapter with expanded production capabilities.
